Hello Franck, glance is not deployed on all nodes at default.
I got the same problem
In my case I have 3 controllers.
I created an nfs share on a storage server where to store images.
Before deploying glance, I create /var/lib/glance/images on the 3
controllers and I mount the nfs share.
This is my fstab on the 3 controllers:
10.102.189.182:/netappopenstacktst2_glance /var/lib/glance nfs
In my globals.yml I have:
This means images are on /var/lib/glance and since it is a nfs share all my
3 controlles can share images.
Then you must deploy.
To be sure the glance container is started on all controllers, since I have
3 controllers, I deployed 3 times changing the order in the inventory.
Or you can deploy glance 3 times using -t glance and -l <controllername>
As far as the instance stopped, I got I bug with a version of kolla.
Now is corrected and with kolla 12.2.0 it works.
